IMPROVEMENT IN BRACES FOR CARRIAGE AND OTHER SPRINGS.

Specification forming part oi' Letters Patent N 111.229, dated January 24, 1871.

I, LUBION C. MILLER, of' Humphrey, in the county of Cattaraugus and State of N ew York,

have invented certain Improvements in Braces for Carriage and other Springs, of which the following is a specification:

My invention is an improvement on my brace patented April 28, 1868; and consists in making the arms, which are secured to the carriage-box, adjustable instead of iixed parts of the brace. By this construction the brace is adapted to any length from the carriagebox to the spring-bar, whereby I obviate the expenseand inconvenience of having various sizes ot' patterns and keeping a large supply of assorted sizes of braces on hand to meet the demand..

To enable others skilled in the art to make and use my improved brace, I will now give a detailed description thereof.

In the accompanying drawing, which makes apart of this specification, Figure 1 is an isomctrical view of a cast-in g, A, composed of the longitudinal bar al and crotchcd arms a2, which project from one end of the saine. Fig. 2 is a like view of the casting B, forming twin arms 0.3 a3. Fig. 3 is a plan view ot' the pieces A B in connection.

Like .letters in all the figures indicate the same parts.

A is a casting, having a longitudinal bar, al, and crotched arms a?, which project 'from one end of the same. -Thc pait al has a hole, b, through which a. bolt is passed to confine the casting to the carriage-box, and the holes c c in the ends of the arms a2 a2 are used for confining the arms to the spring by means of the two bolts by which the spring is 'fastened to the cross or spring bar.

So far the brace is essentially the same as described in my patent above referred to.

IVhat constitutes the present improvement is the construction of the part al without the cross-arms a3 a, and with parallel sides, and the combination and arrangement, with the said part al, of the casting B, which piece is shown detached in Fig. 2, and in connection with the part al in Fig. 3. The said casting B, as seen iu Fig. 2, has a cross-groove, d, which tits on the part al, and by means of which the casting is adjustable on the same, so as to .vary the distance from the said piece B to the holes c c in the ends of the arms a2 a2 of the casting A, whereby to ada-pt the piece to any distance between the carriage-box and the spring-bar. The holes e ein the ends ot' the casting B are used for confining it by means of bolts to the carriage-box.

I make the brace of malleable iron, and hence it will be seen that without the improvement, by which the size of the pieces A Bis adapted to various distances between the carriage-box and the spring bar, much inconvenience would arise in keeping a suitable supply ot` braces on hand, the braces in such cases having necessarily to be of various sizes; and this state of things would involve much greater expense than having but one size of casting el'eeted by the present improvement.

fhat 1 claim as my invention, and desire to secure by Letters Patent, is-

The combination and arrangement of the adjustable piece B, constructed substantially as described, with the piece A, whereby the brace is adapted to various distances between the carriage-box and spring-bar, as herein set forth.

In testimony that the above is my invention I have hereunto set my hand and atiixed my seal this 5th day of December, 15370.`
